The MIC PRO

A Microphone Switching System
that makes low cost production mixing boards act like expensive broadcast consoles.
Designed to control the DM Engineering Studio Slave, Henry Engineering Superelay, or other relay packs.

Available now...The MIC PRO ON/OFF LED lighted switching module, when combined with the DM Engineering SLAVE Studio Auxiliary Relay Pack or any other relay pack with required inputs and outputs (see below), will upgrade a low cost production mixing board to have the microphone switching features of a professional broadcast console. High reliability LED lighted "MIC ON" and "MIC OFF" buttons enable and disable the mic channel(s) so the mic level control(s) can be left at the optimum setting. More than one Mic input can be controlled simultaneously using the MIC PRO and Studio SLAVE Auxiliary Relay Pack or competitive product. Monitor speaker muting and "ON AIR" or "RECORDING" signs may also be controlled via the relay pack. The MIC PRO is attached to the console with the supplied hook and loop fastener system or double sided tape, for a more permanent solution, to the side of the production board as shown below.

For individual control of more than one Mic input or Mic control without using a relay pack, check out the "MIC PRO 2". If Insert jacks are not available on your board check out the Mic-Pod.

Complementary button labeling is available if the standard MIC ON and MIC OFF is not desired. A limit of 2 lines of 6 characters each (including spaces) is allowed. Specify the exact lettering, case and orientation when ordering. The picture above shows vertical orientation.
